Call JL since you spent all that money there... I'm sure he will take care of you...

 

I No What The Codes Are Just Want To No What Would Cause The Problem,,and Ya I Would Love To Bring It Back To Jl It Will Only Cost Me 600 For A Tow There, I Need To No What Sensors Or What Can I Do To Fix It,thanks

 

not for nothing dude but it's KNOW not NO and it's YEAH not YA

 

Know problem dude.

 

thanks for the spelling lesson mom,ok dude

 

i could be way wrong so take it with a grain of salt. Hopefully someone will back me up but i think it would be ur 02 sensor. If u just got the headers put on then it is really possible. Good luck. i hope u figure it out.

Always happy to help a fellow Lightning owner out, and I'm not your mom.

 

maybe the 02 sensor on the long tubes is bad, sometimes the wire melts on the tubes and that could cause it????

 

thanks guys still trying its not the o2s changed them ??????????????
